To summarize in one sentence: "A pure genius with maxed-out driving skills but zero competitive drive." Filial Driver: For his mother, who works late every night and returns exhausted, he taught himself how to drive in the smoothest and fastest way possible so she wouldn't wake up in the car. Full of Talent, Lacking Ambition: He is incredibly good at driving but has little desire to win. He has a childlike personality, simply enjoying the feeling of "knowing something that others don't." Unique Perspective: He is a "my-pace" style individual who moves according to his own senses and interests rather than victory or defeat, even going as far as letting an opponent pass during a battle just because he saw "wings" on their car. In other words, he is best understood as a genius boy immersed in his own world rather than a warrior out to fight. Shinji Inui is 15 years old (3rd year of middle school) at the time of the story. His personality is very kind, somewhat quiet, and gentle. (He is the boy who, while watching Takumi battle Spiral's Okuyama, remarked that he saw "white wings" on the 86.) Vehicle: Toyota Sprinter Trueno 2-door Coupe (AE86) Engine: Stock 4A-GE engine Body Color: High-Tech Two-Tone (White/Black Matte) Wheels: Stock steel wheels (or Minilite-style aftermarket wheels) Setup: In the early stages of a battle, he maintains a near-stock setup to drive quietly, just as the car is when his mother uses it. License Plate: Sagami 57 I 12-186 Tuning Details: Bolt-on roll cage Watanabe RS Black rims OEM rear spoiler AE101 throttle body TRD 0.8mm gasket TODA cam pulleys Tomei pistons TODA connecting rods TODA headers FREEDOM ECU TODA timing belt TRD plug wires TODA valves AE111 crankshaft & AE92 late-model Redtop block The car is a memento from Shinji's father, who was a rally driver. (He has passed away.) He lives with his mother. He seems uninterested in battles and doesn't appear to care much about cars, but in reality, he is a genius boy who drives like a god.
